GAS-WASHER.

Specification. of Letters Patent.

Patented Sept. 29, 1914.

Application led February 10, 19112. Serial No. 676,874.

To all whom t may concern Be it known that I, J oHANN F. M. PA'rrrz, a citizen yof lthe United States, residing at Milwaukee, in the county of Milwaukee and State of Visconsin, have invented a certain new and useful Improvement in Gas-Washers, of which the following is a specification. l Thls invention relates to improvements 1n the construction of as purlers or washers.

The object of the lnvention is to provide a characters designate similar parts.

The single ligure of the drawing discloses a central vertical section through a gas washer showing fragments of the inlet and discharge jipes leading to and from the casing` of same.

he casing 13 is provided with an inlet 33 near its lower end and a discharge 6 lat the upper end thereof. The lower end of the casing 13 is provided with a water seal 34 which serves as a packing for the lower end of the casing. The cap 5 incloses the upper end of the casing 13 and forms a support for the bearing frame 4. The rotor or fan shaft 1 is mounted concentrically in `the bearing frame 4 and casing 13, being vertically Isupported by means of a Athrust bear? ing 3 formed inthe bearing frame 4. The drive pulley 2 is fixed to the upper extremity of the shaft 1 and is adapted to receive rotary motion fromA a motor by means of a belt, not shown.

The fan supporting member 29 is fixed to the lower extremity of the shaft. 1 and carries a series of outwardly projecting fan plates 7, 17, 27. The blades 8, 18, 28, are

attached to the (plates 7, 17, 27, respectively,-

1Q, 110, 210, which are formed with large clrcular inlet openings adjacent the supportfing member 29. These fan plates 7, 17, 27, and balile plates 10, 110,x 210, inclose the blades 8, 18, 28. The inlet 30 of the lower fan connects directly with the inlet 33 to the casing 13. The plates 7, 17, 27, have upper plane surfaces and constitute means having circularly continuous surfaces adjacent their perlpheries.

The casing 13 is provided with angular inwardly and downwardly projecting bathe plates 11, 39, which approach but have central openings which are slightly larger in diameter than the peripheries of the baffle plates 10, 110, respectively. As the thrust bearing 3 is formed of a series of plates, the opening existing between the baffle plates 10,- 110, and the baiie'plates 11, 39, respectively, can be varied by either inserting or removing bearing plates at the thrust bearing 3. The fan rotor. may be bodily removed from above through the central openings in the plates 11, 39, by removal of the cap 5. Nozzles 9 which receive their supply of water from supply pipes 12, are directed inwardly to the spaces formed between successive fans. The nozzles 32, which are supplied with water through the pipe 31, are direct-ed toward the interior of the lower fan, these nozzles 32, however, being unessential. The lower end of the casing 13 is formed with circular recesses 35, 36, which are adapted to receive or collect the downwardly flowing l,water injected through: the nozzles 9, the Iwater bemg carried from these recesses 35, 36, through the pipes 37, 38, to the water seal 34.

During the operation of thev washer, the shaft 1, supporting member 29, and the fans :are given a rapid rotary motion by means 'of power applied to the pulley 2. The impure gas is drawn through the inlet 33 and suction opening 30 to the interior of the first or lower fan b'y the fan action of the of the casing 13 through the nozzles 9 and flows from the upper or first set of nozzles 9 onto the fan plate 17 of the middle fan. The action of centrifugal force causes the water thus thrown upon the plate 17 to be thrown outwardly in the form of a film or thin sheet, so that after leaving the plate 17 it impinges upon the adjacent innerv surface of the casing 13. The water thus deblades 28. Water is injected to the interior posited upon the interior wall of the casing 13 flows down the wall and over the baffle plate 39, from which it flows through the annular space between the baffle plate 110 and the plate 39, to the fan plate 27 of the first or lower fan. Additional water is admitted to the upper surface of the fan plate 27 through the lower or second series of nozzles 9. The water thus deposited upon the plate 27 is thrown outwardly in the form of a film, by centrifugal force and impinges against the inner wall of the casing 13. Upon striking the walls of the casing 13, the water flows downwardly into the recess 36. Since the amount of water admitted to the washing chamber by the nozzles 9 is too great to pass directly through the overow pipe 38, the water rises to a point somewhat above the top of the partition separating the recess 35 from the recess 36, thus also filling the recess 35. The gas discharged from the fan blades 28 causes the upper surface ofthe excess water above the recess 36 to gradually slope toward the outer wall of the casing 13, the angle of slope of this surface. being regulable either by variation in the amount of water admitted to the casing 13 through the nozzles 12, 32,

` or byvertical adjustment of the fan rotor whereby the size of the annular opening between the plate 210 and the adjacent partition may be varied. As the impure gas is discharged by centrifugal force from the first fan blades 28, it strikes the upper surface of the water flowing Ainto the recess 35, and on accpunt of the inclination of this surface of water, is directedupwardly. The vrotar motion of the' blades 18 of the second an produces a suction or reduced pressure in the space between the plate 110 and the plate 27, thus causing the gas discharged .from the blades 28 of the first fan, to pass through the film of water discharged from the fan plate 27, to the space between the lower and intermediate fans. In this space the gas is directly subjected to the spray emanating from the second series of nozzles v 9. The gas then passes to the interior of the second or intermediate fan from whence it is drawn by the blades 8 and is discharged against the sheetyof water which Hows down the inclined plate 39. On account of theinclination of the baille plate 39, the gas is directed upwardly, thus passing in direct contact with the sheet or film of water which flows down the walls of the casing 13 and theplate 39. The reduced pressure in the space between the upper andr intermediate fans caused by the rotation of the fan blades 8, draws the gases discharged from' the blades 18 toward the inlet of the upper fan. In its passage the gas is drawn throughthe film of water discharged outwardly by the fan plate 17, and is further subjected to the sprays of water emanating from the nozzles 9. Upon being discharged from the blades 8, the cleaned gas passes directly through the discharge 6 to the storage reservoir or gas engine. It will thus be seen that the gas after having been drawn into the lower fan, is subjected to the suc` cessive actions of flowing and sprayed waters in the successive fan chambers, thereby removing all impurities and permitting the discharge of purified gas through the discharge 6. The formation of the plates 7, 17, 27, with circularly continuous surfaces adjacent. their peripheries, permits the water leaving the periphery of each of these plates to form a continuous uniform film. The means for vertically adjusting the fans to adjust the passages between the baliie plates 10, 110, and the plates 11, 39, permits the piling up of water to any desired degree adjacent the peripheries of the fans, thus giving a simple means for regulating the amount and. purity of the water suspended within the washer. Due to the fact that direct impact of the fan blades against the gas is avoided, the power required for rotating the fans is also reduced to a minimum.

It should be noted that during its passage through the washer, the vimpure gas is gradually subjected to the cleaning `action of water of different purity, that is to say, the gas having the greatest amount of impurities is brought in contact with the impure water while the relatively clean gas receives .its finalv washing with water which is free from impurities. It is, moreover, not essential to subject the gas to only two cleaning stages as disclosed, since any number of these successive stages could be incorporated.

It should be understood that it is not desired to be limited to the exact d'etails of construction shown and described, for obvious modifications will occur to a person skilled in the art.

It is claimed and desired to secure by Letters Patent,-
